Our EX6 screws are designed and tested by our engineers to meet a variety of customer needs.
Standard Screw (EX6-625): Our standard screw is designed for most PLA and ABS grades typically used for 3D printing, as well as other polymers with a similar melt viscosity. Our standard screw works best with pellets and granules in the 2-5mm size range.
**Pre-Order, shipping 4/15/19** Standard Screw (EX6-625CHR): EX6 standard extrusion screw, upgraded with chrome plating. This new feature provides a slippery surface compared to stock screw this allows for an easy glide of materials. This screw is preferred for tight tolerance extrusion.
Standard Higher Shear (EX6-120-C2): This screw is the same spec as our Standard Screw, only shallower (high shear). This design can improve performance when using powders and smaller pellets (3mm and under).
High Compression Screw (EX6-120-C3): Best for pellets/granules in the 3mm and under range. This screw offers a higher compression than our Standard Screw.
Low Compression Screw (EX6-145-C125): This screw can improve performance with higher melt viscosity polymers which require less compression. Pellets and granules in the 2-4mm size range work best with this screw.
No Compression Screw (EX6-145-C0): This screw can improve performance with higher melt viscosity polymers which require no compression. Pellets and granules in the 2-4mm size range work best with this screw.
